Expedia-owned travel website Orbitz announced on Tuesday that it has discovered and addressed a data security incident affecting hundreds of thousands of users.
In a statement provided to SecurityWeek and other news websites, Orbitz revealed that malicious actors apparently gained access to a legacy platform between October 1 and December 22, 2017. The attackers may have stolen personal and financial data from this platform, which stored both consumer and business partner information.
The breach was discovered on March 1 following an investigation conducted by Orbitz. The company said in contracted forensic investigation and other cybersecurity experts to help it analyze the incident and eliminate vulnerabilities. Law enforcement has also been notified.
Orbitz has highlighted that the hackers targeted a legacy platform and there is no evidence that the current Orbitz.com website is affected.
The investigation showed that the attackers may have accessed personal information submitted by consumers who made certain purchases between January 1 and June 22, 2016. Information on Orbitz partners who made purchases between January 1, 2016 and December 22, 2017 may have also been stolen.
The exposed information includes full name, gender, date of birth, phone number, email address, physical and billing address, and payment card data. The company said the breach impacted roughly 880,000 payment cards.
There is no evidence that passport and travel itinerary information has been compromised, and Orbitz does not store social security numbers (SSNs) for customers in the United States.
“We are working quickly to notify impacted customers and partners. We are offering affected individuals one year of complimentary credit monitoring and identity protection service in countries where available. Additionally, we are providing partners with complimentary customer notice support for partners to inform their customers, if necessary,” Orbitz stated.
“Anyone who is notified is encouraged to carefully review and monitor their payment card account statements and contact their financial institution or call the number on the back of their card if they suspect that their payment card may have been misused,” the company added.
Potentially impacted customers can obtain more information by calling 1-855-828-3959 (toll-free in the U.S.) or 1-512-201-2214 (international), or by visiting orbitz.allclearid.com.
